Natural Dye from Curcuma Longa L. and Its Cytotoxicity and Antibacterial Activities

In the present study, Curcuma longa L. was selected to extract natural dye. The selected plant material was analyzed for its phytochemical constituents, physiochemical properties, antibacterial properties and its cytotoxicity.  For phytochemical test and dye extractions, three solvent systems, ethanol only, 50% ethanol and water were used. Phytochemical test performed on ethanol extract showed that they contained all tested secondary metabolites. The EDXRF results of dye powder expresses it does not contain toxic heavy metal and contains lower mineral contents. The physicochemical property of dye powder expresses it was suitable for dye processes. Cytotoxicity determination was   carried   out   by using the brine shrimp lethality bioassay method. The LC50 values of the extracts were determined by linear regression analysis method. It was observed that the ethanol soluble dye powder LC50 value was 323.752 ppm, which was more potent compared to water soluble potion with LC50 value of 207.182 ppm. The lower concentration of dye powder is suitable for food dye as well as textile dye
